This is certainly no personal attack on Mr Thukral, he may be a terrific talent. But I've rarely seen a management consultant accomplish anything. They may say "you should do this" but rarely stick around long enough to see if it happens. Success is in the details and people who have to execute it. Could be mgmt consultant had great idea which local business did not have ability to execute. Could be the idea was not very good to start with. I've seen both happen in my 30 year career.
When people hire mgmt consultant, they are usually hiring a company name. As in "idea came from Accenture, it must be great!". But those companies never own the result, you do.
